In honour of "Tata" Mandela's 100th birthday, the Bochabela String Orchestra
and the Vienna Boys Choir present a spectacular programme of Western European and African music - featuring the "Nelson Mass"
by Joseph Haydn.
Now in its tenth season, the festival - which takes place in Lungau,
a region of Salzburg - welcomes 51 choirs from Hungary, Norway, Russia, and Austria - and the Vienna Boys Choir will sing
at the opening - suitably "fiery" songs.
